Cherry laurel is rated fire resistant overall, but the sources disagree enough that it should not be treated as reliably fire-safe.
Three assessments favor it: Fire and Emergency New Zealand rates it low on a seven-level scale grounded in shoot-flammability testing, Fire Safe Marin lists it as fire resistant, and Catalonia’s fire services call it recommended. The Catalan verdict is broader than a burn test, combining fire research with fuel structure, maintenance, origin, invasiveness, and professional experience.
Virginia Cooperative Extension reaches the opposite conclusion, giving cherry laurel H, the high end of its three-point flammability scale. That judgment comes from expert-curated landscaping tables in which every listed evergreen tree and shrub received H. Two other findings fall between the favorable and unfavorable sides. The eastern US Firewise plant selector rates it “At Risk” at level 3 of 4, while a southeastern French laboratory study places it in a moderately flammable cluster after testing live leaves for ignition frequency, ignition time, and flaming duration.
These sources are answering different questions under different conditions. A live-leaf test does not cover the same ground as a regional planting guide, and the Catalan suitability rating includes factors beyond flammability. The balance supports calling cherry laurel fire resistant, but only with the qualification emphasized by Fire Safe Marin: placement, spacing, irrigation, and removal of dead material still matter.

The publication is explicitly limited to plants common to Marin County. FireApproved publishes 104 exact owners as Marin regional context while retaining its placement, spacing, irrigation, and maintenance boundary. It is not statewide California guidance or parcel suitability.
Virginia Cooperative Extension's publication opens with Virginia wildfire conditions, identifies its Virginia Firewise Landscaping Task Force, and labels plants native to Virginia. FireApproved publishes 306 exact source owners. Publication scope does not establish parcel suitability or current endorsement of this archived 2009 list.

How to read this page
The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.
Plant hardiness evidence
These values describe the plant source. Your ZIP zone comes from the separate 2023 USDA
Plant Hardiness Zone Map. Whole-zone values stay whole-zone, and a single unresolved value
is not treated as a tolerance range. Different source boundaries stay separate: overlapping
statements are compared independently, while only ranges with no shared zone are called a conflict.

Source location: Cold Hardiness Zone field in the recovered selector record.
Not used for comparison: The recovered selector prints one Cold Hardiness Zone value but does not define it as a minimum threshold or a one-zone range.

These describe tested or rated plant material. They are not horticultural maintenance instructions.
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

The evidence
Grouped by what each source concluded. Primary evidence rated the plant itself
(a lab, field program, or original curation); corroboration compiled or
republished another source's rating and resolves to its root lineage.

Prunus laurocerasus is rated “RECOMENDADA” by the guide's qualitative IUF garden-suitability method. The method assumes species-specific care and integrates fire evidence with fuel structure, maintenance, origin, invasiveness, and expert fire-service experience.
